The RTube is perfect for collecting Exhaled Breath Condensate from humans. As a bonus, Volatile Organic Compounds (VOC’s) which are readily soluble in water can also be easily collected in the RTube as they will naturally dissolve into the condensate. But what...

Measuring cytokine levels in Exhaled Breath Condensate (EBC) continues to be a major objective of breath research. However, there are often substantial data reporting and interpretation differences between research groups making comparisons between studies difficult....

Exhaled Breath Condensate pH is one of the most validated biomarkers in EBC. There are many publications linking low EBC pH to various lung diseases and offering reasons to consider pH as part of an exhaled biomarker study. We won’t be exploring the “why” here; just...

Can a dirty insulating sleeve on the RTube pose a risk of infectious cross-contamination? The RTube itself is a disposable single-use device and is sanitized at the factory to stringent requirements, albeit non-sterile, and shipped in a protective pouch. There is...
